Waveshare Solar Power Manager Module (D) Instruction Manual

Model: Solar Power Manager (D)

1.製品オーバーview

The Waveshare Solar Power Manager Module (D) is a compact and efficient solar charge controller designed for various low-power applications. It facilitates the charging of 3.7V rechargeable Li-ion batteries using either a 6V-24V solar panel or a Type-C power adapter. The module provides a stable 5V/3A regulated output, making it suitable for powering microcontrollers, development boards, and IoT devices.

Equipped with MPPT (Maximum Power Point Tracking) functionality, it optimizes the power extraction from solar panels under varying light conditions. It also integrates multiple protection circuits to ensure safe and reliable operation, including safeguards against over-charge, over-discharge, overheat, and over-current conditions.

4.2接続手順

  1. バッテリーを接続します: Connect a 3.7V rechargeable Li-ion battery to the BATT interfaces (4). Ensure correct polarity. The module does not include a battery holder, so batteries must be purchased separately.
  2. Connect Solar Panel (Optional): Connect a 6V-24V solar panel to the Solar panel charging input (1). The module supports self-adaptive input voltage.
  3. Connect Type-C Power Adapter (Optional): Alternatively, or in addition to solar, connect a 5V Type-C power adapter to the Type-C charging input (2) for battery charging.
  4. 接続負荷: Connect your 5V device to the Power output (3) screw terminal. Ensure the device's current draw does not exceed 3A.

重要： Always ensure correct polarity for all connections to prevent damage to the module and connected devices.

5. 操作手順

5.1 バッテリーの充電

  • ソーラー充電： When a solar panel is connected and exposed to sufficient sunlight, the module will automatically begin charging the connected 3.7V Li-ion battery. The "Charge" LED (part of Solar panel charging indicators, 9) will illuminate. Once the battery is fully charged, the "Done" LED will light up.
  • Type-C充電: Connect a 5V Type-C power adapter to the Type-C input (2). The module will charge the battery. The BATT capacity indicators (8) will show the charging progress.

5.2 外部デバイスへの電源供給

  • The module provides a regulated 5V/3A output via the screw terminal (3). Connect your 5V device to this output.
  • The Type-C port (2) can also function as a 5V output for external devices when not used for charging.

5.3 LEDインジケーター

  • BATT Capacity Indicators (8): These LEDs light up when the battery is charging or under load. They will turn off approximately 30 seconds after the load is removed.
  • Solar Panel Charging Indicators (9):
    • 充電： Illuminates when the solar panel is actively charging the battery.
    • 完了： Illuminates when the battery is fully charged by the solar panel.

6. メンテナンス

  • クリーニング： モジュールを清潔に保ち、ほこりやゴミが付かないようにしてください。清掃には柔らかく乾いた布を使用してください。液体や研磨剤入りの洗剤の使用は避けてください。
  • 接続: Periodically check all screw terminal connections to ensure they are secure. Loose connections can lead to poor performance or damage.
